Consider a shed with an 8-ft×12-ft base and 4-ft height. The temperature of the outer surface of the roof and the walls of the shed is to be maintained at least 20°C on a quiescent night when outside temperature is 0°C and sky temperature is -15°C. What is the total heat loss heat loss from the building?Ignore the heat transfer through the ground. Assume the emissivity of the walls and roofs is 0.75.
